What's Wrong?

In the sidebar version of claud code (vscode) I cant tell what state this button is in.

When you hover it says "Thinking Off".
Given that all the other buttons have titles that indicate what they do I read that as: press to turn thinking off
However, when I press it it gets a barely noticeable background which would suggest an active state and when you hover it says "Thinking On"
Are you using title to display the active state? Its really confusing because the title means do this action in other cases.

What Should Happen?

If the current is the title is saying what the active state is, I would suggest changing it as follows:

Thinking On => Turn Thinking Off
Thinking Off => Turn Thinking On

That way its clear what the action is going to do and what the active state is based on what the toggle action will do.

Steps to Reproduce

View hover of the thinking button in both states.
Thinking as a user who did not build the ui and the titles of other buttons what do you think pressing it will do?
I argue Thinking On suggests strongly that it will turn it on not off and because the styles are subtle it hard to determine what state its in.
